Comparison of pedotransfer functions to estimate the van Genuchten parameters from soil survey information

Kutatasunk celja a viztartokepesseg-fuggveny (VKF) parametereit az atnezetes terkepeink adattartalmaval becslő modszerek megbizhatosaganak osszehasonlitasa es tovabbfejlesztesuk vizsgalata a Magyarorszagi Reszletes Talajfizikai es Hidrologiai Adatbazison (MARTHA).Az irodalomban fellehető modszerek kozul VKF-becslő modszert hazai atnezetes talajterkepi informaciokra eddig egyedul a Kreybig terkepekre alkalmaztak (Bakacsi et al., 2012). Ők a talaj higroszkopossaga (hy) alapjan becsultek adott talaj FAO (1995) fizikai feleseg kategoriaba tartozasat. Wosten es munkatarsai (1999) es Nemes (2003) pedotranszfer-fuggvenyei alapjan rendeltek tovabba a talajhoz a fizikai feleseg kategoriara meghatarozott viztartokepesseg-fuggveny (VKF) van Genuchten parametereit (HYPRES_hy es HUNSODA_hy modszerek).Bakacsi es munkatarsai (2012) eljarasat kovetve, a MARTHA adatbazison vizsgaltuk a hy es az otkategorias FAO fizikai feleseg kapcsolatat. A fizikai feleseg becsleset az Arany-fele kotottseg (KA) alapjan is kidolgoztuk.Wos...
